# Stablecoin Payment Order Message Push

## Stablecoin Payment Webhook

When the status of a stablecoin payment order changes, the system sends an event notification to the merchant’s pre-configured endpoint via **Webhook**.

The webhook mechanism enables merchants to receive **real-time payment updates** without actively polling the order query APIs.

* The webhook payload includes core order information and blockchain-related transaction data
* Merchants should properly handle the webhook request
* A successful **HTTP 200 response** is recommended to acknowledge receipt

***

### Webhook Event
